Conv() not working

I am trying to use Conv function to convolute two distributions. But the Conv function is not working, do I have to install any special tool for it to work. Isn’t it a built-in function?

You don't need a toolbox to run this function. What is the error?

[dinesh kumar mohan]

I used this example as provided by mathworks: u = [1 0 1]; v = [2 7]; w = conv(u,v)

The error I am getting is: Attempt to execute SCRIPT conv as a function

Answer 1

I'm guessing you have written your own script conv.m that's taking precedence over the built-in conv function. To check this run:

which -all conv

If my guess is correct, rename or remove your conv.m script.

Yes, I got it. Thank you very much

Answer 2

Could it be that you tried with uppercase C as in Conv and not with lower case as in conv?

>> conv([1 1],[2 2])

ans =

     2     4     2

>> 

>> Conv([1 1],[2 2])
Cannot find an exact (case-sensitive) match for 'Conv'
The closest match is: conv in C:\Program
Files\MATLAB\R2019a\toolbox\matlab\datafun\conv.m

[Constantino Carlos Reyes-Aldasoro]

ahhhh this may be more subtle! Try the following:

>> which conv
C:\Program Files\MATLAB\R2019a\toolbox\matlab\datafun\conv.m
>> 

If you do not see the same, it is because a) you have another file with the name conv, or you have a variable with the name conv.

Yes I got it, thank you so much

Great! If this is sorted, please accept the answer. If not, let me know.

[Constantino Carlos Reyes-Aldasoro]

ah I see that you accepted Steven's.
